Savior Heated Gloves for Men and Women,Rechargeable Heated Electric Gloves,Suitable for Winter Outdoor Work,Skiing,Cycling,Running,Hiking,etc.

Overall they work pretty well. The battery lasts at least a couple hours (I never timed it though). My only complaint really is that the thick control button should possibly be moved elsewhere. When you grip things the button housing presses into/puts pressure on the back of your hand. This makes it a little uncomfortable. For an average person, maybe you don't care that much. I have arthritis, which is one of the reasons I purchased heated gloves. The location of the button is sometime uncomfortable for me, but again only really when gripping things and it's minor. I will continue to use and overall I'm happy with the gloves.

Charged up the batteries and wore the gloves out to walk my dog the next day in -20 degree temperatures, kept my hands very comfortable considering the temperatures. Toasty warm on any days above zero.
